用失重和表面腐蚀层厚度的测定以及借助于Ｘ光电子能谱（ＸＰＳ）、红外吸收光谱（ＦＴ—ＩＲ）、扫描电子显微镜（ＳＥＭ）等分析手段研究芳烷基酚树脂在浓硫酸中的腐蚀行为。探讨耐浓硫酸腐蚀机理模型。结果表明试样经一定时间浸泡后表面腐蚀层厚度对温度和作用时间没有依赖关系，该材料耐浓硫酸腐蚀。腐蚀机理为：浸泡过程中，试样表面形成了一层结构致密的耐腐蚀物质，阻止了硫酸分子进一步向试样内部扩散渗透，使试样内部免遭进一步破坏。
The corrosion of aralkylphenol resin in concentrated sulfuric acid was studied by measurement of weight loss and surface corrosion layer thickness and by means of X-ray photoelectron spectroscopy (XPS), infrared absorption spectroscopy (FT-IR) and scanning electron microscopy (SEM) behavior. Discuss the mechanism of corrosion resistance of concentrated sulfuric acid. The results show that the thickness of the surface corrosion layer after being soaked for a certain period of time has no dependence on the temperature and the action time, and the material is resistant to the concentrated sulfuric acid. The corrosion mechanism is as follows: During the soaking process, a dense layer of corrosion-resistant material is formed on the surface of the sample to prevent further penetration of the sulfuric acid molecules into the sample and prevent the sample from being further damaged.
